To all whom it may concern:

Be it known that. I, GEORGE J. Timer, 9. citizen of the United States, and 1 resident of Milwaukee in the countyof Milwaukee and State of' Wisconsin', have invented cer tain new and useful Improvements in Methods and Apparatus for Making Reinforced Box-YValls5 and I do hereby declare description thereof.

My invention relates to new and useful improvements in reinforced box walls or" similar structure of that type including ;pa per or otherfabric sheets, between which are secured crossed reinforcing metal strips, and to the method of making such structure, my invention also relating to apparatus for most conveniently and economically carry in out said method. I

t ,isthe object'of my invention to pro-- vide a reinforced structure ofthis character which is of maximum strength consistent with a desired economy and li htness of material and which lends itsel to most economicalmanufacture. a

A further object of my invention is to facilitate the manufacture of such rein-' forced structure by the provision of an ims proved method of forming the structure, wherein connecting portions struck from certain of the reinforcingmembers of the s'tructure serve to assist in assembly of the other reinforcin members of the structure there with. A ther object resides in the provision of a simple apparatus for procuring a most rapid and economical manufacture of the structure in accordance with my im Figure 1 is a side elevatlonal view of machine adapted to carry out my improved Fig. 2 is a transverse sectional view through the machine on a plane indicated by the lines 2-2 of Figs. 1 and 3.

gear 17 thereon meshing with a bevel and having a sprocket connection 20- with the intermediate portion of the main. frame. The standards 15 also carry sliding-boxes 23 resiliently urged end portions of a shaft ear 18 on a main drive shaft 19 extending longitudlnally ofthe machine a motor 21 mounted on a bracket 22 under downward by theare journaled,"the" 25 which is con-1f being nected with and driven from the 'shaftlG" by intermeshing gear wheels 26 of equal size on said shafts.v are mounted on the shaft 16 and these rollers have their eripheralportions engaged annels formed in enacting rollers 28 secured on the shaft 25. 1 These pairs of rollers 27 and 1D. peripheral c taneously 9 28 rec'eivin one ofv i the ribbons 14 therebetween, said ri bon 'be- 3 mg guided by the channeled flanges ofthe roller 28. Thus the ribbons are evenly fed into the machine, and tongues a are simulstruck upwardly at regularly spaced portions of the ribbons,-;by"punch"" projections 29 on the peripheries of the rollers. 27 which 'coact with recesses 30 in the peripheries of the rollers 28,"'said p'rcjec-, 10115 and recesses being regularly spacedabout the peripheries of the rollers, u a 1 These tongues are'adapted to receive the transverse reinforcing stri to procure feeding action'o said transverse strips. Thus; a magazine 31 for thetransverse strips 6, is mounted transversely oye'r' s b,- and serve 110 t A plurality of rollers'271 zine.

6 as they move rearwardly upon the ribbons,

- arms projecting laterally from one of. the side framesills 10 adjacent the magazine. These brackets also carry standards extending throug the sidewalls of the magazine and having their sides under cut to receive the edge por tions of the ribbons, the top of the tongues being guided into said slots by a beveled finger 33 projecting for.- wardly The rear wall of the magazine 1s spaced fromthe bottom thereof a distance from the front wall of the mega:

the main frame forwardly of the roll (Z and a roller 56 isdisposed therein which engages a floating feed. roller 57 that is in turn engaged by material trained forwardly thereover from the roll d, said material being then trained about an idle roller 58 mounted inthe frame and extended rearwardly being thus provided with a coating of paste whereby the reinforcement and both rolls of body sheeting may be pasted together. The websc 'andd and said reinforcement pass between upper and lower pressure rollequal to the thickness of one of the strips ers 59 and 60'carried by standards 62 on the 6. Hence, as shown Fig. 3, as the ribbons move through the magazine, each horizontally alined series of tongues a will engage oneof the strips 6 and force it'from the magazine.

azine and are adapted to engage the strips yieldably holding said strips so that the tongue may move a snug fit of the strips withm the confines of the tongues. The strips are supplied to the magazine from a roll 6 carried by bracket 36 in which are 'ournaled a feed roller 37 driven by a sproc et connection 38 with the main drive shaft'19. The standards also carry sliding blocks 39 urged downwardly by springs 40 and mounting a roller 41'. The ribbon isfed between the rollers 37 and 41 and is extended into the magazine throu h a'throat' carried by the adjacent i end wall thereof. The ribbon is cut into the strips 6, which are stacked in the maga zine by a knife blade 43 movableover the *innerend face of the throat and carried by a lever 44'which is intermediately pivoted on a bracket arm 45 carried by the maga- Zinc. The knife blade is normally urged to raised position by a spring 46 secured to the l, remote end portion of the lever, and the" knife is intermittently operated by a rod i7 V on a stubsha t 50 carried by one side of.

pivoted to the remote end portion of the lever and 'slidable in a guide 48 on the mag'a-. zine, and enga eable by a cam 49 mounted the main frame and driven from'the main 'shaft'by a bevel gear wheel 511thereon meshing sha v The longitudinalribbons a and transverse with a beveled gear 52 on the main strips 6, are connected, together by the tongues a and, for applying body sheeting to both sides of this reinforcement, a roll of paper or other fibrous material ,0 is

mounted between standards 53 carried by the side sills rearwardly of the magazine,

' and a second roll of body sheeting d 1s mounted in hangers '54 depending from the sills. A gluereceptacle 55 is mounted under Downwardly inclined detent 1 fingers 34: extend rearwardly from the mag thereover, thus procuring side. sills rearwardly of the roller 58 and rollc, the upper roller 59 being mounted in sliding blocks 61 resiliently urged downwardly bysprings 63. A pair of upper and lower feed rolls 64 and 65 are carried by standards 66, the upper roll being urged toward the lower. roll by springs 67, the

lower roll being driven by a bevel gearconnection 68 with the main shaft 19.

An exceedingly simple method of forming reinforced box .walls has thus been provided, which may be carried out in a 'convenient manner embodying'the machine dethe parts, which is procured by the coatin of paste supplied to the lower sheeting the transverse strips 1) are positively held within the confines of the ribbon or' longitudinal strip. tongues a.
